What this trial studies

This observational study investigates the role of epigenetic mechanisms in stress intolerance among patients with chronic widespread pain (CWP). It involves a randomized cross-over design with 44 CWP patients and 44 healthy controls, who will undergo mental stress tests and relaxation breathing interventions. Participants will complete questionnaires and undergo various assessments, including blood withdrawals and neurophysiological measurements, to evaluate stress-induced epigenetic changes. The goal is to better understand the pathophysiology of CWP and identify potential new treatment avenues.

Who should consider this trial

Good fit: Ideal candidates are females aged 18 to 70 with a diagnosis of fibromyalgia and a BMI below 30.

Not a fit: Patients with other neurological, endocrine, cardiac, or systemic syndromes, or those with a history of cancer or heart failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of stress intolerance in patients with chronic widespread pain.

How similar studies have performed: While research on epigenetic mechanisms in CWP is scarce, similar studies in other conditions have shown promising results, indicating potential for success.
